and why can't I see an option to boot into recovery mode on my HTC Hero (Orange UK)? Is it already in recovery mode when I can see the Fastboot/HBoot menu? Initial menu after holding vol-down when booting: Initial menu after holding vol-down when booting (click image to enlarge) If I press back, I get the following screen: (Click image to enlarge)
|
"HBoot" mode is something of a misnomer, really, that I usually see when people mean "reboot into your HBoot menu". I think the reason these got conflated to each other is because <code> Fastboot </code> mode activates by default when you land on HBoot on most (possibly all) HTC phones. They do exist separately, though, as devices without an HBoot menu can still have a fastboot mode. This is definitely a little confusing, though, since what's really happening is that you're getting rebooted into HBoot which is then immediately loading Fastboot. You should be able to get to the bootloader's main screen by selecting <code> Bootloader </code> from the Fastboot screen. Essentially, though, HBoot is just a bootloader, which gives you the ability to chain-boot into several other partitions or modes (including fasboot). I say it's not really a "mode" because it doesn't really allow for any interaction, it just loads and waits for you to choose something else from the menu (with one exception, see below). HBoot also has the ability to install a properly named and signed zip file if placed on the root of your SD card, which it will attempt to do right after the bootloader has fully loaded. This seems to have been designed as a sort of last-ditch reflash method, and used to be a part of several manual rooting methods on HTC phones (which is now largely unnecessary). The exact naming convention depends on your device, but they're usually of the form <code> PC[some number]IMG.zip </code> . Fastboot mode is the state your device goes into so that it can accept fastboot commands, which largely deal with manually flashing partitions on the device. Notably, you can flash unsigned partition images when in fastboot. It's handy for recovery purposes, but also useful for development and generally hacking around (depending on what you're doing). You can read a bit about the details of fastboot here . Your "recovery mode" (or recovery partition) is different from HBoot. It is a separate partition on your device which contains a very basic kernel and GUI that can be used to repair and/or restore your system, with the features varying depending on the exact recovery you are using. Typically a manufacturer will ship their devices with their own "stock" recovery, but there are many custom ones available which are more robust. There is a stackexchange-url ("related Android Enthusiasts question") which also discusses this.

Despite the highly praised Nexus One built-in noise cancellation, I need to use speech recognition in an extremely noisy environment with better noise isolation/cancellation. Is there a so called " speech recognition microphone " that would help? I'm not aware of the complexity or performance of the noise isolation algorithm used by the N1, is it as good as I'm going to get?
|
If you are working in a high noise environment, a traditional mic isn't going to help you. Even with a noise cancelling secondary mic it will be very difficult for the equipment to pick your voice out of the noise and isolate it. You might look into a throat mic instead, which grabs your voice by direct contact with you rather than conduction through the air. These are especially suited for noisy environments.

This seems to be a fairly common issue. Upon attempting to charge my Motorola DROID BIONIC with two non-Motorola microUSB wall chargers, I couldn't get the phone past 40%. With the Moto charger, it charges fully (though apparently pretty slowly). I know the BIONIC's battery is a 3.8v, and my chargers are all 3.7, but the voltage difference doesn't seem large enough to cause a problem. Is is possible the BIONIC can read the difference in the voltage, even if it is small, and is coded not to fully charge on these non-Moto chargers? Both HTC chargers I've tried were 200mA. It seems maybe the amperage is too low to charge the phone. I'll try and find a higher power one to test.
|
Does the phone begin discharging at 40%? Does it indicate that it is still charging, but the charge never exceeds 40%? I have had stackexchange-url ("charging issues with my Motorol DROID v1.") What I've come to understand is that the power delivered by the car adapter is less than the power drawn by the phone when the GPS is on. I would suspect that a couple of factors might be in play here: Connectivity problems If the connection between the charging cable and the phone might be poor, perhaps due to poor connector seating or swelling due to heat. It could be that, after charging for a period of time the phone heats up and expands to the point that the connection is lost. The phone stops charging, cools, and the connection is made again. Phone behavior at or above 40% charge Do you have Tasker or some other automation tool running that has rules about which features / services to run at a particular charge level? If so, you could be seeing that the services cause the phone to draw power at the same rate that it is charged, preventing further charging. These are really just guesses. If you have one, I would try hooking up a 3rd party charger that is rated for the same power output. If the phone charges completely this way, even though it is not a Moto branded charger, it is a pretty good bet that your HTC chargers just aren't cutting the mustard with your Moto phone.

Has anyone found out why some BIONICs won't charge fully on non-BIONIC wall chargers?

The stock browser in Gingerbread 2.3.3 seems to take a lot of resources in terms of CPU and memory. This causes other apps, including the launcher, to be killed. Are there any steps I can take to reduce the footprint of the browser? I have a Samsung Galaxy S (AT&T Captivate) running a ROM based on Gingerbread 2.3.3.
|
The only things I know of are turning off images, Javascript and plugins. You probably don't want to do all that but setting plugins to "On demand" is quite useful -- pages with Flash ads and such won't waste your data or battery in addition to demanding less from your phone, and it's just one click to allow a particular object to run if you want to watch an embedded video or something.

Theoretically, it should do this automatically. In practice, sometimes it works, sometimes not. All the pages below have proper favicons, but only the O Globo and Amazon favicons made it to the desktop icon. (The former in a better way, as you can see.) I added them the usual way, with Menu -> Add -> Shortcut -> Bookmark. This is a (rooted) Milestone running Motorola's official 2.2.1 update. These are the pages involved: http://moglobo.globo.com http://cracked.com http://mobile.formula1.com https://mobile.twitter.com http://www.amazon.com http://www.supervia.com.br Any reason for that erratic behavior?
|
It has to do with the site having an icon for "apple-touch" defined in the page. for example O Globe has the following: <code> <link rel="apple-touch-icon" href="favicon.png" /> </code> And it works. There are differences in how other versions of android handle this. Here is an article explaining some how this works a bit. There could also be a "catch 22" to this though, as I see that the mobile twitter site does have the apple-touch-icon-precomposed but doesn't seem to show the icon. This could be because of something motorola did differently in their modified version of android, or it could just be a bug. If the site does not define the icon, then you can use a tool like Any Cut to change the icon.

I'd like to turn LTE on while I'm at work and off at home; I have the appropriate profiles, but I can't find an appropriate action. Is this something that could be done with an intent?
|
I was hoping the "Wimax" or "Mobile Data 2G/3G" Net Actions would be what you need, but after looking around it doesn't look like Tasker supports 4G on/off switching. Per Tasker forum user Pent regarding this issue (on a different phone): If this isn't currently a feature is there any way to implement it? It isn't and there's no 'official' way to implement it. I was hoping there would be something in ICS, but don't think there is after a quick scan. One day I'll have to do some research, but I prefer working on features that will still work going forwards and benefit everyone. Pent Sorry for the bad news.

My kids love playing with my android. However, they don't always understand what they are doing, and occasionally I find that they have deleted some of my apps (strangely, never the ones they play :) ). Is there any app that can make uninstall more difficult, or make access to the apps menu more difficult (e.g. require a PW)?
|
Install Smart App Protector with its helper app (for enhanced reliability). Make sure to make it device administrator. Then, lock <code> Package Installer </code> and <code> Play Store </code> using it (lock down other market apps too). With one tap, the app can lock all apps which could uninstall it. The app facilitates this for its own security, but its solution of your question. And, I can bet... after that your kids can't uninstall an app without developer level expertise. Update: After your comment, looks like your app launcher is capable of uninstalling apps directly like Play Store. So, lock your Launcher too. From your screenshot, its Samsung TouchWhiz launcher having package name <code> tw.launcher </code> . Lock this package with Smart App Protector. But, it'd lock your app drawer too. If you don't want to lock your app drawer, best way is to switch your Home Launcher app & lock <code> Package Installer </code> , <code> Play Store </code> etc. Done! Alternate launcher apps have more features as well as memory efficiency. So, its better in all other aspects. If you don't want to spend money, I'd recommend you Go Launcher EX . If you can spend money for this, I'd recommend you ADW Launcher EX .

I've got one of these folders on my HTC Desire 2.3 and I'm assuming that it's standard across all devices. It looks to contain screenshots of pages that I have visited using the built in browser and I'm guessing that it's to dispaly them in the bookmarks/frequently visited list or when I'm changing windows. My question is is it safe to delete the contents of this folder? It doesn't occupy much space but there are sites in the list that I know I won't be visiting again and it seems pointless having them around.

Yes you can safely delete the folder. For details and a permanent solution (to stop regeneration of this folder) check this

When I develop for my Samsung Galaxy S II, the screen locks as usual after the configured time. However, for development it would be practical if the phone would just stay awake while it is connected to my computer. So, How do I disable the lock-screen when my Samsung Galaxy S II is charging/connected via USB? Question: stackexchange-url ("Display On when plugged in") is not a duplicate, as this solution does not work on the Galaxy S II. Unfortunately.

When I'm on a call my screen turns off after X seconds. Half the time I can't get it to turn back on without pushing the on/off button, which I have set to terminate a phone call (because half the time I can't get the screen to turn back on).

Keep screen on during calls That setting is not available on all phones, but if it was it would be under: Home > Settings > Call Settings > [Display > ] ... But as for the difficulty turning the screen on Be sure that the power button does not end calls (Settings > Accessibility > Power Button ends call : make sure it is UNchecked) Then just pull the phone away and press the power button to turn the screen on.

I used to connect with SSH to school server on iPad with iSSH , which can work as X11 server, and remotely work through SSH and X11 with iPad as a server. I thought since it is easy with iPad, it will be easy with Android. But silly me! It is not, as I see. In stackexchange-url ("this SE question") and on other places, people are telling "don't use X11, just use VNC!". However, I can't see how can I remotely start x11vnc on a machine where I am not a root on. The situation is as follows: I am NOT a root on the server machine. There is linux running on the server machine. I do NOT have physical access to the server. I can connect to the server through SSH. When I log in to the server and I try to run <code> x11vnc </code> like this: <code> x11vnc -forever -shared -rfbauth ~/.vnc/passwd -create </code> I got this scary looking error message after trying to connect with AndroidVNC application (the error is displayed on the server and the x11vnc immediately crashes). If I don't use the <code> -create </code> option, <code> x11vnc </code> shows this scary message and x11vnc crashes before even waiting for the client. So. My question is quite easy. What should I do to connect to the linux machine and do something simmilar to what I did with iSSH and X forwarding? edit: aha, it seems like in our school we use outdated X11vnc version, so that's why it breaks. Awesome. Well, I probably can't persuade the admin to actually update it, so I will need another way of remotely running graphic applications, if nothing like iSSH exists.

I found out that it's possible to just run <code> vncserver </code> on the client - and it "just works".

Back when my HTC Desire had its stock Sense, there was an option to link Facebook accounts to Google contacts, by selecting them from the Facebook friends list. This created fields for my contacts such as: <code> <HTCData> <Facebook>id:02394985720/friendof:2103910923|id:123768123/friendof:09812387</Facebook> </HTCData> </code> Now, my phone is on CyanogenMod 7. I've added a Facebook account under Synchronization settings, but it seems it only matches contacts who have the same name as their Facebook counterpart. Those who are matched get a Facebook profile link: The other ones aren't linked. Therefore: How can I force link a Google contact with a Facebook profile? This would allow me to link contacts even if their names are different. I'm aware of this question: stackexchange-url ("how to link contact with facebook, gmail etc?"), but there is no "Join" option for me, and it isn't really answered as well. I'm also aware of SyncMyPix.
|
First, in the Facebook app, under its Settings, enable synchronization for all contacts. Open up your contact list and select the Google contact you would like to merge. Then push the menu button and select "Edit Contact". Then hit the menu button one more time and select "Join". Choose which contact you would like to merge it with and you should be good to go.

One option: Install ADW Launcher as your home application and set it as default From your home screen press <code> Menu Button->More->ADWSettings </code> to open ADW's settings Select <code> UI Settings->Main Dock Style->None </code> to hide the bottom bar Optionally, you can also select <code> Screen Preferences->Hide StatusBar </code> to hide the status bar at the top, which effectively makes your home take up the entire screen.

When I only have one "desktop" on my Android phone and I select one of my photos for the wallpaper, it asks me to crop the image. The cropping tool only allows an aspect ratio that has nothing to do with the real aspect ration of my phones screen resolution. Why? I have a Samsung GT i5800 running Android 2.1update1.
|
Pretty sure this was present in Eclair (but it's possible I'm mis-remembering and this was a new feature in Froyo) but when you select a picture in the gallery, at the cropping stage it should give you a choice of screen resolution/aspect ratios to use. One of them should be the resolution of your screen, the other one is for the side-ways scrolling multi-screen wallpaper. I've ringed round the two selection options in the screenshot below, tap the wide option on the left for the multi-screen wallpaper and the one on the right to crop to a single screen. You should then be able to drag the crop box out to be the full picture (if you've got the aspect ratio right on your image). Edit: This appears to be a Samsung TouchWiz feature, rather than a stock Android feature, it should still be present on OP's Samsung GT i5800.

This is usual Android disconnection response. It's to do with your phone checking in with the closest Antenna when you end a call.

Today I just make a mistake when typing a text on a box over Android's browser and then I realise that I was missing the "back to past" CTRL+Z Microsoft Windows feature, which allows you to step back anything you made on Windows. So, there is such thing on Android OS?
|
The back button serves as Undo or Cancel (or Back) in many apps, but won't help with a typo in a text box, it's more likely to lose everything you've typed in there than undo the last bit of typing. I don't believe that there's any standard, central Undo function in Android at the moment. As very few devices have a hardware keyboard, and many devices are starting to drop even the four hard buttons, I'm not sure how Undo could easily be invoked/shown to the user. Ctrl/Alt etc key combos obviously aren't practical on a soft keyboard on a 4 inch touchscreen, and I'm not sure how else it would be done except with a dedicated undo button on the phone or the soft-keyboard.

My D2G updated to 2.3 today, and I'm no longer able to tether. Prevously, I had no problem using Wireless Tether 2.0.7 with Android 2.2. Now that I'm on 2.3: Wireless Tether 2.0.7 will start up and I'm able to connect my laptop to its WiFi network, but Verizon redirects me to the self-provisioning page ; I have no internet access. Wireless Tether 3.1-beta6 doesn't work. It says tethering is enabled, but the WiFi network does not show up on any other devices. How can I fix this? Edit: This appears to be a reported issue .
|
I was able to solve this, but it's not pretty. Following the advice in this thread , I applied a hack to the radio that gets Wireless Tether working. Edit: I can confirm this exact procedure will also work on a Droid X. Download and install RadioComm . It worked fine on Windows 7 x64. Open Radiocom. This was the first time I opened the app, and a splash screen asked for me to "select which MA to use." I couldn't find the MA mentioned in the thread in this list, so I just selected 3G All Others (or something like that). Open the Main menu, select MA , Common , MDM 6x00 Chipset Base . Open the Settings menu, select USB , PST USB Driver . Connect phone to computer via USB. Change the phone's USB connection mode to PC Mode . The Radio Detection icon on the right side of RadioComm will turn green. Scroll to the P2K 4 tab. In the STELEM / RDELEM section, tick the Dec Entries radio box. In the text boxes, enter: <code> Element ID: 8040 Record #: 1 Offset: 0 Length: 128 </code> Press <code> RDELEM </code> . It will turn green and the following data should appear: <code> 40767A7733672E636F6D00000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000 </code> Change <code> Element ID </code> to <code> 8041 </code> . Press <code> STELEM </code> . It will turn green. Change <code> Element ID </code> to <code> 8091 </code> . Press <code> STELEM </code> . Change the phone's USB connection mode to Charge Only . Reboot the phone. Install Wifi Tether 3.1-beta6 . In Wifi Tether's settings, change the Device Profile to Motorola DroidX (CDMA) . ( Droid2 does not work.) This is a good time to set your SSID and encryption as well. Done. You can now tether. In case you need to revert the changes we just made, here's the original values: (these are the same on a D2G and Droid X) <code> 8041 </code> : <code> 4064756E2E767A7733672E636F6D000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000 </code> <code> 8091 </code> : <code> 40767A7733672E636F6D00000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000 </code>

I have a Samsung GT i5800 and every time I turn it on, or just put a new SD card in it it says "Media search is running" (@the notifications) - How can I turn this feature OFF? Is it needed? What does it do? Android 2.1update1
|
The media scanner "indexes" the music, videos, images, etc on the sdcard so other apps don't have to scan the entire sdcard to know about them. another feature that uses this is the ringtones/notifications, if it does not scan, you will only be able to select the ringtones/notifications that are located on the device, not ones that are on the sdcard. you can prevent media scanner from indexing a specific folder by creating a file called ".nomedia" in the folder you want ignored. I do not believe that this file is recursive though, so if there are sub-folders, and you dont want them scanned, you would have to create it there too.

Another (even better) option would be to tie a praticular setting to a custom keyboard shortcut. Am I expecting too much? Thank you
|
You could use Manual Intent Shortcuts . It offers to add a custom launcher widget that sends intents defined by you. To launch the VoiceSearch Settings window, do the following: add a new "manual intents shortcut" widget to your home screen enter a name Action = "android.intent.action.MAIN" Component Package = "com.google.android.voicesearch" Component Class (FQDN) = "com.google.android.voicesearch.VoiceSearchPreferences" Leave all other fields empty, uncheck "broadcast" You now have a shortcut to the settings window you want. PS: I used apktool to inspect the AndroidManifest.xml in VoiceSearch.apk (system app, you need root to access it) which lists this Activity.

I installed HTC's official (developer-only) Gingerbread ROM on my HTC Desire, but I'm not too happy with it, since it keeps running out of internal memory. So I've been searching for a way to revert back to the original FroYo firmware, but I couldn't find it. Also, I tried to root my phone so I could install CyanogenMod, but that didn't work: apparently, my firmware is too new. So, what's the best way to revert back to official FroYo? Or, failing that, to root my phone? UPDATE with some context: I never rooted, or tried to root, my phone before this failed attempt, and I only did it because I couldn't find an official means to go back to FroYo. I tried both Revolutionary.io and Unrevoked. The latter complained that my firmware is too new; the former just got stuck while "waiting for fastboot". UPDATE 2 I just tried to install a RUU, but it complains about the boot loader being too new. So no help there, either.
|
I was able to root my phone using Revolutionary.io after all, following the steps described here . However, instead of running <code> ./revolutionary </code> as described on the page, I had to use <code> sudo ./revolutionary </code> to make things work.

My wife bought a LG-P350 phone running Android 2.2.2. Is it possible to set the default calender to use when entering new appointments using the agenda application ? She added the google account of my son to her accounts, and now , every time a new appointment is created, the last agenda of my son's account is selected. I have found no obvious way to change this default. I don't know if this is the stock application of Android.
|
As no one is answering this question, I presume it is not possible. So I looked for another solution and found the Business Calender Free edition . This program not only displays a very nice monthly calender, but , most important, let you choose which colour you want to use for each agenda you want to display. Very impressive indeed. Just thought I'd let you know ...

I'm using Cyanogen 7 on an HTC Wildfire. I find swiping the top of the screen to get into Notifications a bit hit and miss, and too tiring : ) Is there some way to get a notifications shortcut onto the homescreen (or the menu for the homescreen). For example, the Sense ROM had a shortcut to notifications in the homescreen menu, and that was pretty handy.
|
If you're using the default version of ADW Launcher that comes with CyanogenMod 7 then you can add a shortcut to your homescreen fairly easily. Long press on an empty space on one of your home screens and then select <code> Launcher Actions->Open/close notifications </code> to add the shortcut. On older versions of ADW you can also do this, but you have to use a "custom shortcut" instead. Specifically, you long press on an empty space and then select <code> Custom shortcut </code> . Then on the dialog that appears you press the <code> Pick your activity </code> button and select <code> Launcher Actions->Open/close notifications </code> . I'm not aware of any way to make it appear in the homescreen menu, unfortunately. It's one of the only features I miss from Sense.

From the current fallout around DigiNotar (in short, a Root Certificate Authority that has been hacked, fake HTTPS certificates issued, MITM attacks very likely), there are some parts concerning Android (see yesterday's interim report in PDF): fraudulent certificates for *.android.com has been generated (which would include market.android.com) there may be other such fraudulent certificates signed by this CA in the wild (currently nobody knows for sure, one way or the other) this could happen to another CA in the future (Comodo had a similar problem a few months ago) So, how do I remove a CA I no longer trust from my Android phone? (I have root and CM6 on my specific phone, if that's relevant)
|
Lookout Mobile has blogged about this due to the DigiNotar events, and provided some pretty good (read: lengthy) instructions which you can find here . The gist of it is that you need to pull <code> /system/etc/security/cacerts.bks </code> and then remove the CAs from the store, then push the store back to the device and reboot. Their instructions require that you have Bouncy Castle (for decrypting the store), root access, and a working adb connection. I'm not sure if this applies to all versions of Android or not, but my guess would be that the location of the CA store hasn't changed in quite some time (if ever).

Basically what the title says. I rooted my phone with unrevoked (I am not sure if I used the "forever" version or not). Will installing the 2.3.4 Gingerbread OTA update from Verizon remove my root? I'm not running any special ROMs if that makes a difference.

You almost always lose root when installing an OTA update. I would keep an eye on RootzWiki or DroidForums for someone to confirm that it can be rooted or someone to release a rooted update.

I have a Samsung Mesmerize and I've recently upgraded to my carrier's official release of Android 2.3.4, but to my dismay SuperOneClick doesn't seem to be able to root the device, it's always worked with past versions. Does Gingerbreak no longer work with 2.3.4? Is there any simple way to root 2.3.4 yet without reflashing and other device changes? I would like to avoid reflashing the device again or altering the device from stock significantly if at all possible.
|
The SuperOneClick dev's website http://shortfuse.org/ states on their August compatibility list : All 2.3.4 devices need a custom root method. Looking around, there doesn't seem to be a universal one click root method for 2.3.4 yet, most of the root methods for the later Gingerbreads involve flashing custom firmware, etc which is more involved.

I've started using Google Plus and I want my Android "contact" picture to change to the picture used in G+; a real photo of me. It's currently using an old avatar picture I once set for Google Talk, so when I call them it pops up with a silly avatar instead of my real photo. This shows up as my Phone contact picture as well, not just Google +. Is there some way to set which image is used either via android, Gtalk or Gmail or something? I always use Gchat via Gmail, but I don't know where or how I set my Gtalk avatar anymore, and I don't recall setting that picture for myself on my phone ever. I am on Android 2.3.4.

I have MIUI 1.7.22 Italian installed on my HD2 running from SD card. I found that there is version 1.8.5 available from the MIUI updater program on the phone. However, even if I download the ROM it doesn't get installed. It asks me to reboot in bootloader mode, so I suppose it works only with NAND-installed ROMs. Do you know if it's possible to upgrade MIUI to 1.8.5 when running from SD card possibly without erasing all data on the phone?

You can write, compile and distribute native code as an Android Application. Look here for more info about the NDK. If you want it done without the official framework and application packaging then you'll need to look into cross-compiling the application for the ARM architecture.

I have a non-rooted T-Mobile G2x by LG running Android 2.3.3. I have had it about two weeks and have noticed several problems. Randomly shuts down. I go to use my phone and it doesn't come on, I press the power button and nothing happens, unless I long press which makes the phone boot. This has happened 3 or 4 times. The battery has a good state of charge, it's happened just sitting on my desk as well as when I wear it on my belt. It's also done this in the middle of a voice call. Runs slow. I turn on the phone, the screen comes on, I swipe my unlock pattern, nothing happens for 2 - 10 seconds, then it shows me the pattern and unlocks the phone. It takes several attempts to unlock the phone because it doesn't always see the whole pattern. I swipe correctly the phone just doesn't pick it up. The phone has locked up a couple of times, the screen is blank, playing with the power button does nothing. The only way I have been able to get the phone to come up is to remove and reinstall the battery. The only thing I have noticed when it runs slow is I seem to be running out of ram. Less than 10%. If I kill the apps, it runs fast again, until the ram is gone which only takes 2 - 3 minutes before all of the apps using RAM have restarted. Should I take the phone back to T-mobile and exchange it? If so any tips? I can just imagine the bureaucracy that I will have to deal with to get this accomplished.

I have a follow-up to the question posted stackexchange-url ("here"). I recently got a 2.3 DroidX phone, and noticed that it as well has data encryption option. I pulled an SD card from device, and noticed that folder structure is intact. I tried reading file from the SD card, which was produced by a photo application, and it was unreadable, however the file itself contained some data which was not random , which to me indicated that not the whole file was AES'ed. I was also able to put an unencrypted file on SD card which was readable afterwards. So, the question is: does anyone know what encryption methodology is being used here, what algorithms are in place, and how strong they are against experienced attacker? EDIT : My friend got a droid2, which also runs gingerbread 2.3.3, and it has data encryption feature too. So... is data encryption an android feature or specific to Motorola devices?
|
Apparently, DroidX uses ecryptfs Following are mount options on /data/data: <code> rw,nosuid,nodev,noatime,nodiratime,ecryptfs_sig=****************, ecryptfs_cipher=aes,ecryptfs_key_bytes=32,ecryptfs_passthrough </code> I would imagine this means that encryption key here is 32 bytes, which is 256 bits, which seems pretty good to me.

Pure Calendar Widget (not free) has an option for how many days ahead to show calendar/task entries for. There is an option for 2 days that would suit your needs perfectly.

I have a rooted Samsung Galaxy S2 running the stock Samsung ROM (no custom ROMs ever). Of late, I notice that every few minutes, a toast pops up saying 'Refreshing SIM data'. If the screen had been blanked earlier, it reactivates, and this is annoying, especially at night.

Update - Have upgraded to 2.3.5 Gingerbread and with different kernels ( Ninphetamine and DarkyROM SuperCore ) but it makes no difference. I wonder if it's because of the service provider.

I'm currently living in China, so I bought my Asus Eee Pad Transformer 101 here. For some reason it does not come with the official Google Marketplace application but with some other application that only supports chinese as a UI language and uses some other "less official" market place. I did find the Market App from google and installed it. However when I start it it tells me You must add an account to the device to continue. Do you want to add one now? If I click Yes, I'm simply redirected to the home screen (the app remains open in the background) Does anybody know of a way to set this up? Because the only thing was able to add to the device was my gmail account for e-mail. Thnx.

Apparently there is no way to do it. There are some alternative market places that can be used, but they don't solve the fact that tablets with the chinese firmware are rendered useless because there's no Google account support. So the only thing you can do really is install this: http://forum.xda-developers.com/showthread.php?t=1245892 Works like a charm :) Oh and for the Prime, Asus officially supports it.

You can close all the pages via Menu -> Windows before exiting the browser.

In other words, use only lightweight apps or don't use anything, and hope your system behaves :P

I was having that problem, and the solution that helped me was to charge up the battery completely, then use the recovery boot menu to wipe battery stats. Then, I used the phone until the battery died and the phone shut itself off. During that time, it is important to not plug in your phone to USB or charger, it has to drain continuously. Then you can charge it back up again and use it as normal. It should help to make the battery percentage more accurate, and to drop in a more stable way.

I want to install Darky ROM to replace my stock Gingerbread phone. Can I do this without Odin, using CWM, or will that only work if I have a previous version of Darky?
|
If you have a working CWM or 2e recovery you can flash Darky's with it just fine from a stock ROM. If you have a lagfix, particularly the ext2 OCLF, be sure to undo it first. (It appears Darky's uses the Voodoo ext4 lagfix, so no need to disable Voodoo beforehand. See stackexchange-url ("Is the Voodoo lagfix compatible with Darky's ROM?"))

I have an SGS with stock Gingerbread (2.3.3). Can I install CWM without Odin? Will installing CWM also root the phone, or do I have to root it ahead of time?
|
You need Odin in order to install CWM without root (or conversely, you need root to install CWM without Odin). CWM does not root the phone. You don't need root for ClockworkMod Recovery, though you do need root for the ROM Manager app. Edit: You can't install unsigned packages with the "3E" recovery, which was part of some official update packages (most Froyo ones and presumably all Gingerbread ones). This prevents one from flashing a custom ROM, kernel, modem, or recovery through the stock recovery (since they aren't signed by the manufacturer). The way to get around this is normally to use Odin to flash a custom ROM or kernel with a custom recovery. I'm not sure if flashing a signed update to an older official ROM, with the older recovery, would work; it might say it's older than your current version and fail, or it might just work. I've never been able to try it, and I'm familiar with Odin anyways.

Does flashing a new kernel require flashing a new ROM? Will flashing a new kernel wipe the data? Because if so, I might as well flash a new ROM. How can I see which kernels are compatible with which ROMs?
|
Does flashing a new kernel require flashing a new ROM? It depends. You can't normally flash a 2.3 kernel over a 2.2 ROM, and so on. You can't flash a CyanogenMOD kernel on a stock ROM in most cases, and vice versa. But you should be able to flash any Android X.X stock-based kernel over any Android X.X stock-based ROM. For example, there are no issues flashing a 2.2 Voodoo kernel on my 2.2 stock-based Bionix ROM for my SGS Vibrant. Will flashing a new kernel wipe the data? Not usually. When flashing a lagfix ROM such as Voodoo that does advanced partitioning and formatting, there can occasionally be issues that will make you lose data. As well, update packages can include scripts to automatically wipe the data. You should carefully read the official description of any kernel to see if it mentions wiping data. I've flashed dozens of kernels and only lost data once, and that was probably my fault; I had a fairly non-standard configuration. It's always good to do a backup if you can. Some ROMs recommend or automatically perform data wipes to eliminate any incompatible data between the two ROMs, but this is normally not an issue for kernels. How can I see which kernels are compatible with which ROMs? Again, any ROM based on stock is normally compatible with any kernel based on a stock kernel fromt the same Android version. If you have concerns I would first search the XDA posts for the kernel and the ROM to see if you can find anyone who has used them in combination.

I have a few WiFi network in the neighborhood and the Nexus S will always detect those networks that I never use. However, for my own WiFi network, it randomly fails to recognize the network, even though I sit right next to the router. I know that everything else is OK, because I can access the network through my laptop, and if I just restart the router, the phone will start to pick up the signal again. I think there might be something wrong with my router, because I never have that problem with the network at work. The only difference I can think of is, I turn off my router right when I stop using WiFi... What might be wrong? Is this a known bug? Are there workarounds (that does not involve restarting the router? Update: I do find some clue. If I turn the router on before turning on wireless on the phone (via the power management widget), then things work just fine. If I turn on wireless on the phone before the router, I'll need to restart the router. I don't know how much sense it makes though.
|
I've found the problem. Both the router and the phone was working correctly. The problem is with the Wifi channels. According to Wikipedia's List of WLAN channels , some places only allow channels 1-11, some others 1-13. Devices will provide support accordingly. My router supports channels 1-13, while the phone (I guess) supports channels 1-11. So when the router uses channels 12 or 13, the phone cannot detect the network! Solution? Buy another router which only support channels 1-11. Logon to your Routers config through your browser to find whether the router supports limiting the channels. Refer to your Routers user manual on how to do this Change the channel settings on the router to be manual (i.e not automatic), and somewhere in the range 1-11 (preferably 1 or 6 or 11).

I'm currently running the latest stable release of CM7 for the HTC Droid Incredible and Facebook for Android 1.6.4 (released on 20 August). According to Facebook, push notifications are enabled for devices that support them. Since I get push notifications from other applications (such as Google+), I know my device supports them. I've read about various problems with them, but I haven't found any definitive solutions (or a definitive lack of a solution). I would assume the setting for push notifications would be in the application's Settings menu. I have a number of options for various times to pull notifications down, but I don't see an option for push notifications in the app or on the Facebook website. Is this just a broken application or am I missing something?
|
Funnily enough, as I just noted stackexchange-url ("here") I believe that the app is just buggy and unreliable. There's no reason for the individual device to determine whether the application can do something like push notifications. Android's cloud to device messaging requires 2.2 or higher, and the Facebook post notes that that's what they require as well, so I assume that's what they're using. C2DM works perfectly fine for other apps so the only reasonable explanation is that the Facebook app doesn't work properly. The app was updated recently and does work better for many users, though, so make sure you have the latest version. There are no settings related to push messages in the app or in the Accounts and Sync settings. Regular sync is every 3 hours at most, which seems infrequent to me — my BlackBerry allows updates every half hour.

It looks like the Market is currently blocked in UAE and this has nothing to do with your phone. It may become available soon but I've not found anything with a date. I have seen that it's not so much the government blocking it as an inability to bring banks on-board. This thread suggests that you can get around it with a dial code, but it looks like it needs a hard reset. There are also other questions here about installing the app manually, like: stackexchange-url ("How to install android market app manually?")

I have purchased some ebooks which I have received in both EPUB and MOBI format. Can I read these MOBI or EPUB files with the Kindle application ? I copied the MOBI files into the kindle folder, but they do not show up in my Kindle main screen.
|
I will answer my own question in the hope in helps others: I just had to reboot my device, and now when I start Kindle the MOBI files which I had copied to the Kindle folder are present in the main screen. So obviously the Kindle application must be restarted when you add ebooks to its folder (without downloading them via the Kindle store). UPDATE Added the Kindle folder: <code> /sdcard/kindle </code> Force closing and/or clearing the data, does not bring up an EPUB file I just copied to the folder. Will let you know after some more testing. UPDATE 2 For those interested: the Calibre software , can convert any e-book between numerous formats (including EPB and MOBI). So, if the EPUB format is not recognized, just convert it to MOBI and use the converted file.

Waking up in the morning to a very bright screen is no fun. I'd rather the screen be dimmer in my dark bedroom when I wake up. While I could manually change the brightness before going to bed and changing it once I get up, it's too much bother. How can I automate changing the screen brightness based on the time of day?
|
If you don't mind paying a few bucks, I highly recommend Tasker . This automation utility allows you to set up many built-in (and some 3rd-party app) Android actions based on various parameters, including time of day. In Tasker you will need to create 2 separate profiles, and to each add 2 actions. 1st action will be identical in both profiles - disabling the Auto Brightness. Second one will be similar - a time-based action to change the display brightness, with time of day and brightness level being the differences. Start Tasker and tap the <code> + </code> button on the bottom o the main screen to create a new profile. Give it a descriptive name, such as "Brightness Down" for example. Choose the "Time" context on the presented menu. For the "From:" option select the time of day you wish to have brightness lowered. Un-check the "To:" option, and tap the green "Accept" button. On the "Task Selection" dialog tap the "New Task" button and name it "Lower Screen Brightness" and tap the "Accept" button. Tap the "+" button to add an action, select "Display" category, select the "Auto Brightness" action, select the "Off" option on the "Set" drop-down, and press the green "Accept" button. Tap the "+" button to add another action, select "Display" category, elect the "Display Brightness" action, set the desirable low level (20 being the lowest recommended setting), ensure that both "Ignore Current Level" and "Immediate Effect" options are checked, and tap the green "Accept" button. Tap the green "Accept" button on the "Task Edit / ..." screen. On the main screen tap the "Brightness Down" profile once, then tap on its wrench button, and select the "Clone" option. Tap the newly-cloned profile, tap its wrench button, select the "Rename" option and name it "Brightness Up". Tap on the clock icon, select the "Edit" option, change the "From:" time to the time of day when you'd like brightness increased, and tap the green "Accept" button. Now tap on the task itself (name you gave it in step 5), select "Rename" option, name it "Increase Screen Brightness", and tap the green "Accept" button. Tap the task again, and select the "Edit" option. Tap on the "Display Brightness" action, set the Level to a higher setting, and tap the green "Accept" button. Tap the green "Accept" button on the "Task Edit / ..." screen. Ensure that on the main screen, the button on bottom-right reads "On", and exit the Tasker app. You should now be all set.

I have a Samsung Galaxy Tab 10.1 tablet. I love it. I think Google's default honeycomb UI is fine, but Samsung wanted to improve upon it with their own UI called "TouchWiz". Following an annoying trend however, they released their device before their software was finished and promised to provide the new UI and software enhancements in a future update. Well, that update is now available, and my tablet has been nagging me for more than a week to apply it. I keep hitting "postpone". If the update includes bug fixes or improved functionality, then I might be better off applying it. But I'm a bit worried about performance. It seems to me that alternative home screen managers, Windows explorer shells, browser toolbars, and other UI "enhancements" available on the various platforms tend to bog down the system, put their little hooks into everything, and just generally get in the way. I'm also worried that applying this patch might disable something in the vanilla functionality that I need. I haven't heard that that's the case, but it's not unusual for manufacturers to turn off functions that the vanilla Android OS has built in. So, what I'd like to know is, will applying the software update for the Samsung Galaxy Tab 10.1 cause any issues that I'd want to know about? Will it hurt performance? Will it take up tons of system resources? Will it disable features I need? I'd love to see a post-TouchWiz review of the machine from a major tech publication, but I haven't found one yet.
|
Well, nobody seemed to be able to answer this question, so I went ahead and applied the update. Overall, I'm glad I did. I haven't noticed any significant change in performance. I could take or leave most of the UI changes included in Touchwiz, but there are a few things in the new UI that are very nice. One is that toggles for things like bluetooth, wifi, and auto-rotation are now immediately accessible in the notifications pop-up when you touch the notification tray. Another nice thing is a dedicated screenshot button that appears next to the regular android buttons in the control bar at the bottom. Press it at any time for an instant screenshot. I haven't noticed that any features have been disabled. I don't have a 3G-capable tablet, so I don't know if the "portable wi-fi hotspot" functionality would be affected by the update. But everything else I've tried functions as it did before. Also, an unexpected bonus to the upgrade is that Samsung released a bunch of new apps bundled with the new UI, some of which are very useful. The ebooks app especially is nice for me, it reads EPUB and PDF files, and it formats EPUBs better and performs faster than some of the other apps I've tried (like FBReader). There's also an app for making adjustments to photos, and a few others that I haven't really used. The new TouchWiz UI also includes a handful of mini-apps that can be launched from the android control bar at any time. These apps appear in small windows that float over whatever other apps you're running, and they can be moved around. None of these apps are really awesome, but some are useful. For example, you can bring up a mini-view of your calendar, a small music player, or a note pad you can type into or draw on, without leaving the app you were using before. It's kind of a neat idea, although I'm glad this isn't a standard android feature or there would be way too many apps written this way, and Android would lose a lot of its ease-of-use.

After some problems I had to restore my phone. Before doing it I had enabled the option of google's security copy. Now I've linked my google account and market does nothing, it doesn't restore apps. So I've decided to enter the market through the browser and in "My market account" I could only see the three apps that are native to the phone (youtube, gmail and google maps). How can I get all the apps I had before? Thanks, Diego
|
Did you look in your " Library "? I recently did a factory reset and I can see all of the apps that I'd previously had installed, not just the ones I've only just gotten around to.

When generating an intent in an application that is supposed to create the dialog popup to choose an activity to complete the action, it simply doesn't show. I get a darkened screen and no dialog. For example: click on a YouTube link should popup a dialog asking to use Browser or YouTube (if no default is set). When I click on this link, the screen darkens like it wants to show a dialog, but it simply doesn't.
|
Solution: apparently there is a bug with this in Android 3.2. Rotating your Xoom will fix it.

I've just got a HTC sensation and I've worked out how to change the icons on the home screens, but is there a way to change the icons on the lock screen?
|
Yes, this is possible without apps . The icons on the lockscreen are the same ones that you chose for the home screen: Here you see the icons I originally had on both screens: By changing the apps on my home screen adjacent to all apps, this change is mirrored on the lock screen: To change the icons adjacent to all apps on your home screen, long-press them until you can move them around then drop the old icons either into the trash can (that appears when you long press) or into a free space on another part of the home screen. You can then replace it with an icon of your choice.

I added my Facebook account to the calendar to sync up my Facebook friend's birthdays in my calendar. But along with the birthdays, few useless events also got added automatically. Like if my friend who is a football fan, is attending a Football match somewhere, that event is displaying in "MY CALENDAR". It is very annoying to see my friend's events in my calendar. How do I stop that?
|
Has your friend invited you to the event? I've never seen my friends' events in my calendar, only when they've invited me too. For these events you need to remove the event by going to the event's facebook page, scrolling all the way down and clicking the "Remove from My events" link in the footer. Facebook won't sync the RSVP info for some reason, so "Hide declined events" in the calendar options won't hide events that you're not attending (which is very annoying by the way).

How can I clear my DNS cache on my android phone? (Droid3, Gingerbread, rooted to be specific) Ideally I'm looking for a command to run through a terminal emulator, something similar to <code> ipconfig /flushdns </code> On a windows machine. What's the Linux version of this?
|
On a typical Linux system the cache is cleared by running <code> /etc/init.d/nscd restart </code> , but at least my ROM doesn't use nscd to cache DNS. You can check if yours does, but I doubt it. I've seen suggestions that clearing the brower cache would clear DNS cache too, but one sure way is to do a hard reboot (shutdown, remove battery for 30s, reattach battery and boot).

I have an issue with the Dalvik cache getting huge and occupying almost all of the space on my phone. I'm running Cyanogenmod 7.X. For the record, I have about 5-6 small applications on my phone (keyboard, voice choice, Gmail, etc.), but I'm showing about 187MB used and 9.7MB free on my internal storage in "Manage Applications". I simple <code> du -h -d 1 / </code> reveals: <code> 0 /sd-ext 0 /config 32.3M /cache 0 /acct 3.5G /mnt 120.8M /system 0 /sys 112.0K /sbin 0 /proc 178.3M /data 0 /root 0 /dev 3.8G / </code> Then, a <code> du -h -d 1 /data </code> reveals further: <code> 550.5K /data/tombstones 13.5K /data/backup 10.5K /data/dropbear 50.5K /data/anr 4.0K /data/secure 413.0K /data/system 94.3M /data/dalvik-cache 3.5K /data/property 6.6M /data/app 1.5M /data/app-private 74.8M /data/data 6.5K /data/local 2.0K /data/lost+found 46.5K /data/misc 2.0K /data/dontpanic 178.3M /data </code> The "cache" is taking up 94.3MB of my internal phone storage?!? How does this make any sense? I did a cache wipe, but it was all regenerated on the next boot. Another really weird but interesting thing is that if I do <code> du -h -d 1 /data/data </code> , I see that many of the apps I have moved to SD storage are still being stored on the phone!!! <code>

<code> /data/dalvik-cache </code> contains optimized bytecode of each installed app. <code> /data/data </code> contains settings and preferences of each installed app. Neither of these two locations are touched when you move the app to SD Card using Gingerbread's built-in methods. That's a limitation of Android's implementation of moving apps to SD. CyanogenMod 7 allows you to move more apps than the stock ROM, but on phones with limited storage you will still eventually run out of space on internal memory. Since you are rooted and already running CM7, take a look at S2E. This app allows you to move both <code> /data/data </code> and <code> data/dalvik-cache </code> to your SD Card. The only prerequisite is that your SD Card must be re-partitioned to add a second Ext2/3/4 partition, after the main FAT32 one. There are many partition tools available (free and paid) that can do this for you. I personally use PartitionWizard's MiniTool Partition Wizard Home Edition (Windows, freeware). It is also recommended to use a stand-alone USB SD Card reader for repartitioning as opposed to built-in readers on most laptops, since those tend to not properly write partition tables to SD Cards. P.S. Don't forget to back up the contents of the SD Card before attempting to re-partition it, since it will wipe all of your data from it.

I'd like to SSH into my phone, download an APK, and install it remotely. Is there a command available on the phone that would allow me to do this?

In adb shell or terminal emulator (and most likely over SSH) you can use the <code> pm </code> utility to install apps. The command is: pm install /sdcard/app1.apk The following are the switches of <code> pm </code> : <code> usage: pm [list|path|install|uninstall] pm list packages [-f] [-d] [-e] [-u] [FILTER] pm list permission-groups pm list permissions [-g] [-f] [-d] [-u] [GROUP] pm list instrumentation [-f] [TARGET-PACKAGE] pm list features pm list libraries pm path PACKAGE pm install [-l] [-r] [-t] [-i INSTALLER_PACKAGE_NAME] [-s] [-f] PATH pm uninstall [-k] PACKAGE pm clear PACKAGE pm enable PACKAGE_OR_COMPONENT pm disable PACKAGE_OR_COMPONENT pm setInstallLocation [0/auto] [1/internal] [2/external] The list packages command prints all packages, optionally only those whose package name contains the text in FILTER. Options: -f: see their associated file. -d: filter to include disbled packages. -e: filter to include enabled packages. -u: also include uninstalled packages. The list permission-groups command prints all known permission groups. The list permissions command prints all known permissions, optionally only those in GROUP. Options: -g: organize by group. -f: print all information. -s: short summary. -d: only list dangerous permissions. -u: list only the permissions users will see. The list instrumentation command prints all instrumentations, or only those that target a specified package. Options: -f: see their associated file. The list features command prints all features of the system. The path command prints the path to the .apk of a package. The install command installs a package to the system. Options: -l: install the package with FORWARD_LOCK. -r: reinstall an exisiting app, keeping its data. -t: allow test .apks to be installed. -i: specify the installer package name. -s: install package on sdcard. -f: install package on internal flash. The uninstall command removes a package from the system. Options: -k: keep the data and cache directories around. after the package removal. The clear command deletes all data associated with a package. The enable and disable commands change the enabled state of a given package or component (written as "package/class"). The getInstallLocation command gets the current install location 0 [auto]: Let system decide the best location 1 [internal]: Install on internal device storage 2 [external]: Install on external media The setInstallLocation command changes the default install location 0 [auto]: Let system decide the best location 1 [internal]: Install on internal device storage 2 [external]: Install on external media </code> For example, you can force the app to install directly to the external storage (Froyo/Gingerbread style.) P.S. The <code> wget </code> utility should be available via BusyBox on CM7. If not, you can always install it via Android Market.

I have a Samsung Galaxy Mini running Android 2.3.3 Gingerbread. In the previous version Froyo (2.2.1) when I held down power button I got in that menu a shortcut to enable packet data. In Gingerbread I couldn't make this shortcut appear. Is there anything I can make to add this shortcut there?

It's impossible to add any custom shortcuts to Power button menu. Looks like you have installed some custom ROM. If that is the case, you could also try to find the ROM which has this feature embedded. Here's the list of custom ROMs for you phone: XDA-Developers: all samsung galaxy mini custom roms! The ROMs that are based on CyanogenMod (CM) have nice feature called Notification Power Widget, it can be customized and Mobile Data switch could be added: If you don't want to change the ROM, you still have some options: As mentioned in stackexchange-url ("another comment") to your question, you could use Power Widget , also Android Market contains lots of widgets specially for Data switching. Also you can simply automate the actions you want to do with stackexchange-url ("earlier mentioned") Tasker or Llama , which is free alternative to the Tasker. With this apps you could set Mobile Data to be turned on or off depending on events like your location, or, screen on/off, etc.

I can see from reviews other people have given to apps in the market that at the very least your account name is made public. However, I was wondering: Is that the only thing made public? If I only give a star rating to an app (but no comment/review), is this anonymous? Is there any way to leave anonymous review comments (i.e. without visibly associating your account name with it)?
|
Your device name is also made public. But, it can be faked easily. As Play Store doesn't display who has starred, you'd be anonymous if you give star rating only. But, nothing can be said for future. I believe, Google stores this data and it can be made public based on TOS and PP we accepted in the beginning. No. Currently, there's no way to leave review comments anonymously.

I can currently access my Android via VNC on my iPad. Can I set the screen resolution of the Android to be the same as the native iPad resolution, giving me a pseudo Android tablet? Even if there is an answer which corrupts the screen on the phone itself is fine, seeing it will be accessed via the tablet.
|
No, you cannot change the resolution of Android in VNC in a standard way. However, some Android phones have additional functions to support HDMI (which results in running Android at a higher resolution). If you can somehow tap into that functionality in conjunction with VNC, then you might be able to get a 480p, 720p, and 1080p option. But this is something that would be highly customized to a single phone as all of the different HDMI implementations seem to vary tremendously. One other option that would be yet another one-off possibility (with some custom work) would be if your phone supports WebTop functionality. If so, perhaps you could tap into this. However, there is no third-party app that does what you're wanting. To do this, you'll have to develop or find somebody to develop this highly-customized solution. As other have suggested, you're probably not going to get much better than changing the LCD Density, which clearly isn't what you're after.

We have a Samsung GT i5800 with Android 2.1update1. When I put a memory card in it, it recognizes it, great! But: When I want to connect the phone via USB to my PC: this picture DOESN'T comes up: And I can't see my memory card through my phone from my PC! On other phones, the memory card is OK. (tried another android phone). The USB cable is good, tried it with another phone. What could be the problem? Are there any settings that I missed?
|
You should check your USB connection mode. This can be found in <code> Settings -> Wireless and network -> USB Settings </code> . This should be set to <code> Mass storage </code> to access the memory card. Alternatively, you can use the debugging mode by selecting <code> Settings -> Applications -> Development -> USB debugging </code> . After this plug your phone in to the USB, open the notification bar and tap the USB debugging notification to get to mount your drives.

Is it possible to send / retrieve MMS messages via WiFi or is it mandatory to be connected to my provider via the mobile data connection? If a user has an active WiFi connection, what happens when there's an incoming MMS?
|
It could be done technically. AFAIK all communication between MMS enabled components is done via standard TCP/IP. But in a regular provider setup the MMS store and forward server(s) (MMSC) are only reachable via the providers network. That's why you can not send and receive MMS via WiFi. It's also the reason why you can not make a call and send/receive an MMS simultaneously when you have only 2G (GPRS/EDGE) connectivity. Normally android will drop the GSM data connection if there is WiFi connectivity and all data will be routed through the WiFi interface, but there is one exception : The MMS traffic will still go through the mobile data connection.

When you create a new event, you should be able to select which calendar to add the event to. If you select an Exchange-based calendar, the event will be synced to the server. By default the events are created in the phone's local calendar.

My Android phone connected to Facebook and grabbed all my friends. Now I want to edit their info and add a mobile number, but it does not let me do that; it only lets you change their ringtone and a few other little options. I am also using GO Contacts from Go Launcher. It's a little annoying when I click "edit a Facebook contact" and it goes to the phone's default contact sheet. If I click a person I input manually it will go to that person in the Go Contact app and give me extra options and all that good stuff. Is this a problem with Go Contacts or something? Can anyone recommend something better? Needs to have a dark skin.

From your contact list, select the Facebook contact that you would like to edit. Click the menu button and choose Edit Contact. You'll see an indication that the user is a Facebook contact and may not be edited. Now click the Menu button again and choose New contact. This will create a new contact in your address book and merge the Facebook profile information with that contact. You may now edit the contact to have additional details, such as a phone number.

According to the "OS Monitor" app, the core "search application provider" is eating most of the CPU on my HTC Incredible S. There are multiple log messages with the following error : "Failed allocating fieldDir at startPos 0 row 10845" where the row value keeps increasing followed by another error "not growing since there are already 10846 row(s), max size 2097152". I have disabled all search plugins and reset the cache, is there anything I can do to stop the "search application provider" eating my CPU and degrading the performance of my other apps (these errors coincide with jerkiness and slowdowns in other apps)

I believe the 'search applications provider' has something to do with google's internal phone data / app search apk Either way: Have you tried going into: Settings > Applications > Manage Applications > Google Search Choose 'Clear Data' and also 'Clear Cache'.

Can Skype be used for video calling on a Samsung Galaxy 10.1? I have been googling, but the results are not clear, for example, the official Skype Blog says that Skype 2.1 supports the Samsung Galaxy Tab, but it is not clear if this means that it works with both the 7" and 10.1" versions. Update: as of early 2012, Skype does work on most Android tablets.
|
The official Skype app currently does not support video on NVIDIA Tegra 2 chipsets, according to their FAQ : * This specifically does not include some tablets that use the Tegra 2 chipset (e.g. Android tablets and Motorola Atrix do not support video calling). From what I read on various forums, a test version that does work on Honeycomb tablets sporting Tegra 2 has been seen floating around in Youtube videos, so it should be coming to official channels shortly.

I'm in the market for a new phone (from my faithful Nexus One), and the Infuse 4G looks like a good candidate. I'm shopping for hardware, of course, as software is never the issue with Android. Is there a way to install Cyanogenmod on the Infuse 4G yet? I've always used that ROM in the past as it's by far the best, and I don't want to upgrade the hardware in order to downgrade the software to AT&T bloatware. Is there a way?
|
Although Infuse 4G is not officially supported by CyanogenMod yet, there are quite a few Gingerbread (Android 2.3.x) based ROMs for it available on XDA Developers forums . An unofficial port of CM7 is currently under development for Infuse 4G. If you are feeling adventurous, and are somewhat knowledgeable in Linux, you can compile your own version of it from latest sources, as described here .

Hi guys i've been trying for quite a while to unlock the bootloader of the phone i've bought. It's from hong kong and branded to vodafone it's not sim locked as I tried an optus sim and it worked. I press and hold the search button and plug the usb in and I get a blue light but when I try to check if fastboot can find it, it can't. Any ideas what the problem is?
|
If fastboot from your computer can't find it, try following these steps exactly, beginning with installing the <code> Requirements </code> below. The most likely problem is some sort of driver missing, disallowing the computer from reading the phone in while it's in the bootloader. This guide can be found on addictivetips.com, and uses a fastboot program from your computer to unlock the bootloader: Requirements: Fastboot package . Sony Ericsson USB drivers (32bit & 64bit) . A functioning internet connection. Steps: To begin, navigate to this website: http://unlockbootloader.sonyericsson.com/instructions . Click Continue at the bottom of the page and enter your device’s IMEI code, name and email address in the relevant fields. Your unique unlock key will now be mailed to you. Now unzip fastboot.rar and open the folder extracted. Within that folder, hold the Shift key and press the right Mouse button. Now select Open command window here. Now we need to connect the phone to the pc in fastboot mode. Do so by turning the phone off, holding the menu button (search button for the Xperia Play) and plugging in the USB Cable. Now in the command prompt, enter the following command: <code> fastboot.exe -i 0x0fce getvar version </code> Now enter the command, replacing KEY in the string with the unlock key mailed to you: <code> fastboot.exe -i 0x0fce oem unlock 0xKEY </code> That is it! The bootloader is now unlocked.

My Galaxy 5 has this problem for some months now: wifi stops working, I try to enable it and the phone says "Error" without any other further information. The only way to make it work again is rebooting the phone. I think this problem has been related here before. But I managed to save the system log and got the following: <code> 08/04/2011 23:01:50 [ERROR] WifiService(166) setWifiEnabledDialog: true 08/04/2011 23:01:50 [ERROR] WifiService(166) ****************setWifiEnabledDialog(), allowWifi****************true 08/04/2011 23:01:50 [INFORMATION] WifiService(166) setShowAccessPointListDialog():true 08/04/2011 23:01:50 [INFORMATION] WifiService(166) setWifiEnabledDialog(): true 08/04/2011 23:01:50 [INFORMATION] wlan_tool(11010) wifi loading 08/04/2011 23:01:51 [INFORMATION] wlan_tool(11014) Driver is initialized. load it 08/04/2011 23:01:51 [INFORMATION] wlan_tool(11021) ar6000 driver fails to load 08/04/2011 23:01:51 [INFORMATION] wlan_tool(11029) wifi unloading </code> I'm trying to understand what's going on here. What exactly is ar6000? Maybe the network interface? How can I get more information about the error itself? I have already uninstalled almost any app that could change the wifi behavior, and the problem persists. Juice Defender is still installed, but the problem already existed before I first installed it.

I've seen a number of people report that the WLAN test dialer code will allow the driver to reload properly (example). I believe it's <code> *#*#526#*#* </code> on many Samsung phones, but this post indicates that it may also be <code> *#*#528#*#* </code> or <code> *#*#232339#*#* </code> . This may not work on all devices, since manufacturers tend to include/remove different dialer codes almost at a whim. If you're unfamiliar with dialer codes, simply open your dial pad and enter the sequence as though you were attempting to dial the number <code> *#*#526#*#* </code> . Your phone should then jump to the WLAN test facility.

I am in the market for a tablet. However I am not clear the degree to which the hardware will be linked to a specific android version. For example, if I get the Motorola Xoom or the Galaxy Tab 10.1, will I be able to upgrade it to honeycomb 3.2? Will there be limitations on future upgrades, and if so, on what time scale?
|
There's really no way to answer this question. There are devices out there that got to version 1.6 and are at the end of the line. I have a DROID with Froyo (2.2) and don't expect to get any more OS updates. It all depends on the hardware and, most importantly, how much effort the manufacturers and/or carriers want to put in to update the device. If the past is any indication, the answer there is "not much". They seem much more interested in selling their new phones. While Google and the manufacturers recently met and said that there will be more of an effort to support and update devices for at least 18 months, we've not seen the results of that. While they occasionally backpedal on announcements of "no more updates" it hasn't been very frequent. If past performance is any indication, I think you can expect a few point releases, and perhaps a full release (to version 4.0) but beyond that I don't think is going to happen. This is, of course, speculation, and this is now a fairly long non-answer answer to an unanswerable question.

My phone updated to GRJ90 about two weeks ago and now I can no longer use WiFi hot-spot or USB tethering. When I try, my 3G connection is dropped. After disconnecting and waiting a few minutes, it comes back up. I used to be able to tether before the update. How can I bypass this, or stop the 3G from disconnecting when tethering. Sprint tells me that I need to pay for a hot-spot plan for $30, but there has to be a way around this besides rooting my phone and putting Cyanogen on it.

|
Sprint tells me that I need to pay for a hot-spot plan for $30, but there has to be a way around this besides rooting my phone and putting Cyanogen on it. Sprint clamped down and disabled the previously free built-in tethering with the latest update . If you want USB tethering you can try PDANet , but wifi tethering will almost certainly require you to root, as it does on other devices. Even with root, you don't necessarily need to use CyanogenMod if you don't want to, though; you could just as easily install a free tethering app ( one example ). This has been covered here a lot, in fact, so you might want to take a look at any wifi tethering apps noted in other questions. See also: stackexchange-url ("Is there a way to enable WiFi-tethering without root access?")

Another thing that you may want to uncheck is the alerts for open wireless networks and forget all the networks your phone has already connected to, as most Android phones are, by default, set up to re-connect to wireless networks they've already connected to. You can find these options, as Matthew Read said above, under Settings > Wireless and Network.

Unfortunately the emulator is extremely slow on all platforms. Better hardware will only get you so far.

How can I make my android (Samsung Galaxy Tab) synchronize with both calendars?

I recall having this issue with some calendar not showing up. If I remember correctly it had to do with having some calendar disabled/hidden in google calendar at the time of the first sync; the calendar app would then not bother looking for other calendars. Try going in Settings > Accounts and Sync > Auto-sync and uncheck it. Go to google calendar on the web, make sure all your calendar are visible. Then in Settings > Applications > Manage Applications > All > Calendar Storage > Clear Data Back to Settings > Accounts and Sync > Auto-sync , check it.

tl;dr : What bad things will happen if I do a factory reset? So I've had this original Droid for about a year and a half. I love this phone, and if only I could get it to be a bit faster and have a little more internal memory I'd keep it forever. However, it had been around for quite a while before I jumped on the Android bandwagon and it's getting pretty creaky in the joints. Further, my contract isn't up until next April. Over that time I have installed and uninstalled a lot of applications (often to answer questions here or, more likely, from recommendations here). I have tried no fewer than five different home screen launcher apps. I have streamlined the apps I'm using and moved everything possible to the SD card. Still, performance just isn't that good. I don't want to root (although I've considered it), but I need this thing to carry me for eight more months. Could a factory reset possibly help? What is the downside to doing a factory reset? I'm not concerned with losing anything important. Between the Market and AppBrain I have no fear that I won't be able to get key apps back. I also have all of my important data syncing to the cloud so I've no worries there. Is there anything lost that I can't recover myself? For instance, am I going to have to go back to the Verizon store and have them reprogram my phone number? Is there any reason I shouldn't just go ahead and to the reset? Update : So I took the plunge yesterday and everything worked out fine. I use Google 2-factor authentication, and that complicated things a little bit. Once I got past that it has been fine. I have quickly the discovered the apps I really need, and have been enjoying much "snappier" performance. I'm just sorry that I can't accept multiple answers. These have all been very helpful.
|
You'll be in the clear for the most part. I factory reset my Moto DROID v1 a few months back, and while it is a little scary to do a total wipe like that, you really have very little to lose. Like you say, you'll be able to redownload any app that you have previously purchased, and your contacts / e-mail should sync back up just fine. It is a little frightening to see the commissioning screen on first boot, but you'll get past that quickly. Like you, I had tried clearing out as much as I could and getting "lean", but I still saw a big performance boost after resetting. One thing you will want to be certain to do is save any text or MMS messages that you have received to your SD card. These get stored in system memory by default and will be erased if you don't save them to the SD card first. You can save an image attached to a text by long pressing the image. You'll get a pop-up with the option to save it to your SD card.

So I just got my wife the Asus Transformer and for some reason there is no Facebook app available in the Market... She can use the web site, but chat is not available there as far as I can see. Any good solutions for this problem? :)
|
The Facebook app ( at least as of July ) simply doesn't support the Transformer. It's pretty bad on a tablet anyway, and I don't even use it on my Xoom. However, some solutions you could try include: Try to download Facebook from a different app store (Amazon, SlideMe, etc). You may also be able to use Market Enabler, though I'm not sure if it will bypass device restrictions. There is stackexchange-url ("a question that discusses this already"). You could try the <code> about:debug </code> trick to switch your useragent to "Desktop". That is discussed stackexchange-url ("here"). This works on my Xoom and allows me to view the chat bar. You can install Opera Mobile and then go into the Settings and select the "Desktop" user agent (Press the "O" button, then <code> Settings->Advanced->User Agent </code> ). This also works on my Xoom. Other browsers also allow you to switch the User Agent string, so these may also work (Dolphin, for example). You can use a third-party IM client like Trillian , which supports Facebook accounts. Facebook chat is, I believe, XMPP under the covers, so other chat clients will probably also work. If you want a tablet-oriented Facebook app, I recommend Friend Me , though it does not currently support Facebook chat. Friendcaster also has a beta version for tablets that you can try out.

When I plug in my Samsung Galaxy S (Model SAMSUNG-SGH-I897, Firmware 2.2, Kernel 2.6.32.9, Build FROYO.UCKB2) to a computer, it starts charging, but does not recognize the USB connection for data. I have tried toggling debugging, mass storage, and ask on connection, but all that happens is that it draws power. I've tried both Windows 7 32bit and Ubuntu 11.04 32bit. It was working yesterday. Additional note: dmesg, lsusb, and adb do not recognize the device at all under ubuntu Thanks

This has happened many times to me, and every time it has been a bad cable. If you have one, try finding another USB cable to test it with, and see if it works. Often some connection goes bad in the cable just from use and wear and it will only charge and refuses to transmit data. The other possibility (this is known to be a problem with the EVO 4Gs, but i don't think i've heard of it on the Galaxy S) is that the USB port on your phone has been damaged or gone bad. This happened to my dad's phone (EVO) and they sent him a replacement. Let us know what happens after you try a new cable!

I love Google's Voice Actions ! It lets me listen to a song of my choice by simply saying <code> "Listen to <song name>" </code> . Problem is... I can't find any way to start Voice Actions itself by voice. I must touch the screen in order to start it. So, my question is two-fold: Is there a way to start Voice Actions by voice? (or without having to touch the screen) If there isn't, what kind of a solution or workaround can you suggest for a blind person? For example, some phones have only one tactile button (other than the power button, of course) -- the trackball. Is it possible to set that trackball to start Voice Actions when pressed long enough?
|
Not that I'm aware of. Presumably you could create an application that listened to the mic all the time and triggered it (voice search) on a certain phrase, but as voice to text is done "in the cloud" it would require a huge amount of data to go back and forth to accomplish this. One shudders to think of the implications on non-unlimited data plans, not to mention what it would do to your battery life. Many phones launch voice serach when you press the button on a bluetooth headset. YMMV , try connecting a bluetooth headset and see what happens when you press the button. another forum thread about launching search from a headset

I don't know even thats possible in case of Xperia mini pro. When I flashed Cyanogen ROM into my Xperia Mini Pro, I was able to customize the notification bar. I mean I was able to change the background color, time color and even was able to show the seconds counter beside the time. Is there any system level application that does the above job on regular(Original) ROM on Xperia Mini Pro ?
|
I was under the impression (before stumbling upon this solution) that the notification system was a part of the secured Android system, and would only be available for modification while rooted or modded. This little application, Notification Toggle , gives you the power of notification power widgets without root privileges! As far as graphical and design changes, the most likely solution is a custom ROM, and you will most likely not be able to do this without rooting and flashing a ROM. Note: this app does not seem to enable you to change the lookout of the notification bar, which, upon second reading of the question, sounds like most of what you are looking for. i was excited about this app, so i felt compelled to share it, but i don't believe it allows for cosmetic changes to the notification bar :/ sorry!

When I use Google Maps for my Samsung Galaxy S , after a while the display goes dark and the GPS disconnects. Is there a way to disable the display countdown during the usage of Google Maps?

I use the Tasker application to change the screen timeout and brightness (as well as the GPS) when I use Maps or Navigation. I turn on GPS and disable timeout when starting Maps/Navigation and turn them off on exiting. Tasker allows you to specify certain tasks that are activated when opening/closing and application. It has several other features and uses, but I find it works well for the problem you are having.

Right now I have in my phone the stock rom and I haven't rooted it. I want to root it and change the rom. What should I do first, root or flash the rom? I don't want to lose all the configuration, apps, apps data or files (images, music, videos, etc in the SD). How can I do to be sure to avoid this? I want to make sure I can go back to the stock rom if I need, is there any special thing I should do? If its relevant, I have a Samsung Galaxy I5510. Thanks!

You should flash the ROM first, unless you need root in order to flash it. (You can flash via Odin without root, but you need ROM Manager, which needs root, or something to flash if you don't use Odin). When you flash a ROM that's rooted, your device will be rooted; if the ROM is not rooted, the device will not be rooted. You need root to make a full backup. See stackexchange-url ("How to backup an Android device?") If you root first, you can install a custom recovery (e.g. ClockworkMOD, via ROM Manager) that will let you create a Nandroid backup of the full ROM. That said, with a Samsung device you don't need to do this. You can use a tool called Odin to reflash the original firmware as long as you've found it for download somewhere. If you need more details on anything I've mentioned, I suggest searching first -- we have lots of questions on rooting, backups, Nandroid / Clockwork / ROM Manager, and Odin. See also stackexchange-url ("How do I root my device?"), which has some info on considerations and things you can do before rooting.
